Product overview


The Tensormeter is designed for automated precision measurements of resistances and voltages. It unites the benefits of Lock-in Amplifiers and Source/Measure Units through an innovative flexible architecture based on an integrated matrix switch. Tensormeter RTM1 enables the automated recording of the complete Resistivity Tensor (Rx, Ry, RH) with one single device, even on unpattern thin films. With excellent AC and DC performance, it covers the range from Nano-Ohm to Giga-Ohms with at least 8 digits of dynamic range.

Tensormeter is designed for automated precision measurements of resistance and voltages.

It unites the benefits of both Lock-in Amplifiers and Source/Measure Units through an innovative flexible architecture.

Tensormeter can be used for thin film characterization, wafer and device testing as well as materials research.
